The Owens River is a river in eastern California in the United States, approximately 183 miles (295 km) long. It drains into and through the Owens Valley, an arid basin between the eastern slope of the Sierra Nevada and the western faces of the Inyo and White Mountains. The river terminates at the endorheic Owens Lake south of Lone Pine, at the bottom of a 2,600 sq mi (6,700 km2) watershed.
The Mohave tui chub is a species of fish. It is an endangered chub originally found only in the Mojave River. Even though named after the Mojave River, the fish's name is normally spelled "Mohave". It was named by ichthyologist Robert Rush Miller.
The Alvord chub is a rare cyprinid fish endemic to the Alvord basin in southeastern Oregon and northwestern Nevada, U.S., known only from a few springs, streams and marshes in the Sheldon National Wildlife Refuge, and one location elsewhere.
The Utah chub is a cyprinid fish native to western North America, where it is abundant in the upper Snake River and throughout the Lake Bonneville basin.
The tui chub is a cyprinid fish native to western North America. Widespread in many areas, it is an important food source for other fish, including the cutthroat trout.
The humpback chub is a federally protected fish that lived originally in fast waters of the Colorado River system in the United States. This species takes its name from the prominent hump between the head and dorsal fin, which is thought to direct the flow of water over the body and help maintain body position in the swift currents of the Colorado. The body is almost entirely scaleless, retaining only about 80 mid-lateral scales along the lateral line. The fish is very streamlined, with a thin caudal peduncle and a deeply forked tail. The back is a light olive gray, the sides silver, and the belly white. The dorsal fin usually has nine rays, and the anal fin 10 or more. Maximum recorded length is 38 cm.
The bonytail chub or bonytail is a cyprinid freshwater fish native to the Colorado River basin of Arizona, California, Colorado, Nevada, New Mexico, Utah and Wyoming in the southwestern United States; it has been extirpated from the part of the basin in Mexico. It was once abundant and widespread in the basin, its numbers and range have declined to the point where it has been listed as endangered since 1980 (ESA) and 1986 (IUCN), a fate shared by the other large Colorado basin endemic fish species like the Colorado pikeminnow, humpback chub, and razorback sucker. It is now the rarest of the endemic big-river fishes of the Colorado River. There are 20 species in the genus Gila, seven of which are found in Arizona.
The Sonora chub is a species of ray-finned fish in the family Cyprinidae. It is found in Mexico and the United States.
The Yaqui chub is a species of freshwater fish in the family Cyprinidae. It is found in northern Mexico and the United States. The Yaqui chub is a medium-sized minnow fish that historically occurred in streams of Rios Matape, Sonora, and the Yaqui systems of Sonora, Mexico. It is one of the five species of the genus Gila in Arizona. The Yaqui chub is closely related to G. ditaenia, and G. orcutti ; and shares several physical characteristics with the G. orcutti, but proves different by having a black wedge near the base of the caudal fin.
The least chub is a species of ray-finned fish in the family Cyprinidae, the only member of the genus Iotichthys.
The hornyhead chub is a small species of minnow in the family Cyprinidae of order Cypriniformes. It mainly inhabits small rivers and streams of the northern central USA, up into Canada. The adults inhabit faster, rocky pools of rivers.
Rush Creek is a 27.2-mile-long (43.8 km) creek in California on the eastern slope of the Sierra Nevada, running east and then northeast to Mono Lake. Rush Creek is the largest stream in the Mono Basin, carrying 41% of the total runoff. It was extensively diverted by the Los Angeles Aqueduct system in the twentieth century until California Trout, Inc., the National Audubon Society, and the Mono Lake Committee sued Los Angeles Department of Water and Power (LADWP) for continuous low flows in Rush Creek to maintain trout populations in good condition, which was ordered by the court in 1985.
The Ana River is a short spring-fed river in south-central Oregon. It is on the northwestern edge of the Great Basin drainage. It flows 7 miles (11 km) from springs at the foot of Winter Ridge through high desert, range, and wetlands before emptying into Summer Lake. For most of its course, the Ana River flows through the Summer Lake Wildlife Area, which is maintained by the Oregon Department of Fish and Wildlife. The river provides habitat for many mammal and bird species, as well as several fish species, including the rare Summer Lake Tui chub. The largest hybrid striped bass ever caught in Oregon was taken from Ana Reservoir in 2009.
The Summer Lake Wildlife Area is a 29.6-square-mile (77 km2) wildlife refuge located on the northwestern edge of the Great Basin drainage in south-central Oregon. It is administered by the Oregon Department of Fish and Wildlife. The refuge is an important stop for waterfowl traveling along the Pacific Flyway during their spring and fall migrations. The Summer Lake Wildlife Area also provides habitat for shorebirds and other bird species as well as wide variety of mammals and several fish species. The Ana River supplies the water for the refuge wetlands.
The Death Valley freshwater ecoregion is a freshwater ecoregion in the western United States. It consists of endorheic rivers, lakes, and springs in the drainages of the Owens, Amargosa, and Mojave Rivers, in central-eastern California and southwestern Nevada.
Taylor Creek is a 2.2-mile-long (3.5 km) northward-flowing stream originating in the Fallen Leaf Lake and culminating at Baldwin Beach at Lake Tahoe, about 1 mile (1.6 km) west of Camp Richardson in El Dorado County, California.
